WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 406,780, dated July 9, 1889. Application filed March 8, 1889. Serial No. 802,558- (No model.)

To all whom, it nzay concern:

provements in ater-Closet Bowls, of which the following is a full, clear, and exact description.

This invention pertains to that class of water-closet bowls known as short hoppers, and having a flushing-rim and an opening for discharging the contents of the bowl, which is located in the bottom and toward the rear wall of the bowl and is in direct communication with a discharge way or passage. The discharge opening and way are adapted to secure standing water in and a trapping of the bowl at its discharge-opening; but heretofore, owing to the construction of the bowl at its discharge-openingand otherwise, and also to the arrangement of the discharge-way relative to the discharge-opening, only an area of standing Water practically limited to the area of the dischargeopening can be secured or increased to any practical extent beyond that area-as, for instance, by raising the normal water-level of bowl. Then the contents of the bowl cannot be practically and successfully discharged.

The desirability and advantages of increasing the area of standing water in these bowls have long been manifest, and by this invention, as practical use proves, an increased water-area is most efficiently, practically, and successfully obtained.

Under this invention the discharge-opening of the bowl is situated in the bottom of the bowl, and it is elongated. The discharge passage of said discharge-opening rises to a level above the level of the discharge-opening, and its axial plane is coincident or substantially coincident with the vertical plane of the longer axis of the discharge-opening, so as thereby to secure a trapping of and standing water in the bowl to a height above the level of said discharge-passage, and the bowl at its inner surface, from below or near the flushing-rim to a horizontal plane below the level of the standing water of the bowl, and preferably to a horizontal plane below the dip of the trap of the discharge-o1: ening,

and in the vertical plane of the longer axis of the discharge-opening and directly at each side of said plane, slopes generally downward, and above the level of the standing water of the bowl and for a portion of its said downward slope it has a direction more or less approaching a horizontal plane, and such asto lead the water running from the flushing-rim downwardly over it off of it, and thereby to discharge and drop it directly onto the standing water of the bowl, all substantially as hereinafter described.

In the drawings forming part of this specification, Figure 1 is a central vertical section from front to rear of the hopper or bowl. Fig. 2 is a plan View, and Fig. 3 is a horizontal section, line 3 3, Fig. 1.

In the drawings, A is a water-closet bowl of the class known as short hoppers.

B is the flushing-rim, and O is the connection by which to connect it with a water'supply, and D is the base of the bowl, all as ordinary and otherwise as may be suitable, and forming no part of this invention.

E is the discharge-opening in the bottom or lower portion and near the rear wall H of the bowl. This opening E is elongated-that is, of gneflr length in one direction between E E than in a direction at right angles to its direction of greater lengththat is, between E E and it is of curving outline, except at its end E toward the rear of the bowl,which is straight, but which also may be curving. This discharge-opening E continues in a discharge way or passage F, which leads downward and thence upward back of the rear wall of the bowl and above the horizontal plane of the discharge-opening, and thence as may be desired. The axial line of the discharge-passage is coincident or substantially coincident with the longer axis or diameter of the discharge-opening, and preferably, as shown, both are coincident with the central vertical plane from front to rear of the bowl.

The downward and upward run of the discharge-passage F to a plane above the horizontal plane of the discharge-opening of the bowl secures a water-trapping of the discharge-opening and standing water in the bowl to the level of the height to which the discharge-passage rises above the horizontal plane of the discharge-opening. The inner surface Gof the bowl, and in the vertical plane of the longer axis E E of the discharge-opening E of the bowl and directly at each side of said vertical planaand from below or near the flushing-rim of the bowl, to and through the forward end E of said longer axis, andpreferably to a horizontal plane below the dip of the trap of the discharge-passage of the bowl, slopes generally downward and above the level of the standing water of the bowl, and for a portion, as at G of its said downward slope it has a direction more or less approaching a horizontal plane, and all substantially as shown in the drawings, more particularly Fig. 1, whereby the water in running from'the flushing-rin1 to the discharge-opening and over said downward-sloping surface of the bowl is led off more or less in a horizontal direction therefrom and discharged and dropped directly onto the standing water of the bowl.

The inner surface of the bowl for its whole perimeter, otherwise than as particularly described and as well known, has generally a downward slope to the discharge opening, and it is of a curving outline in all horizontal planes, graduated between the larger circumference just below and of the flushingrim to the smaller circumference at the discharge-opening.

The elongated discharge-opening E, discharge way or passage F, and inner surface G of the bowl, all as described, secure standing water at and a trapping of the dischargeopening and an area of standing water,which is of substantial and practical increase as compared with that obtainable in a hopper in which the discharge-opening is of the same diameter at all points, and also from the downward slope of inner surface of bowl continued below the horizontal plane of the discharge-opening, and in conjunction with the coincidence or substantially coincidence of .the axis of the discharge-passage with the longer axis of the discharge-opening, the discharge of the contents of the bowl on flush-- ing the bowl is effectively, practically, and successfully secured, all and severally obviously important, advantageous, and desirable results.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, is-

In a water-closet bowl of the class known as a short hopper and having means to flush it, an elongated discharge-opening E in the bottom of the bowl, a discharge way or passage F, leading from said opening and coincident, or substantially so, with the longer axis E 111 of and rising to a height above said discharge-opening, and a slope G of the inner surface of the bowl, in the vertical plane of the longer axis of said dischargeopening and directly at each side of said plane, which has generallya downward direction from below or near the flushing means to a horizontal plane below the horizontal plane of the discharge-opening and above the level of the standing water of the bowl has a portion G of a more or less horizontal direction, substantially as described, for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

WVILLIAM SCOTT.
